Linear vs logarithmic scales. 1  Human hearing is better measured on a logarithmic scale than a linear scale. 2  On a linear scale, a change between two values is perceived on the basis of the difference between the values.  On a logarithmic scale, a change between two values is perceived on the basis of the ratio of the two values.
Antimony has been known since ancient times. It is sometimes found free in nature, but is usually obtained from the ores stibnite (Sb 2 S 3) and valentinite (Sb 2 O 3). Nicolas Lemery, lÃ©mery A french, chemist was the first person to scientifically study antimony and its. compounds
Antimony is a chemical element with symbol Sb (from Latin: stibium) and atomic number 51.ntimony has two stable isotopes: 121 Sb with a natural abundance of 57.36% and 123 Sb with a natural abundance of 42.64%. It also has 35 radioisotopes, of which the longest-lived is 125 Sb with a half-life of 2.75 years. In addition, 29 metastable states have been characterized.
